Functional Diagram
General Description
The HMC610LP4(E) is a true RMS power detector
capable of providing a ±1 dB measurement dynamic
range of more than 70 dB. It converts any RF input
signal at its differential input, regardless of modulation
or waveform complexity, to an accurately scaled linearin-dB output response that is equivalent to the RootMean-Square (RMS) of the input waveform.
For normal operation, the RMSOUT pin is shorted to
the VSET input, and will provide a nominal logarithmic
slope of 37 mV/dB and an intercept of -70 dBm for
frequencies up to 2 GHz; other slopes are achieved
with external resistors connected between RMSOUT
and VSET pins. Temperature stability is excellent
with ±0.5 dB error from -40°C to 85°C maintained from
100 MHz to 3.9 GHz.

should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
